Specification of Letters Iatent. Application filed February li 1914.Serial)? 0.816513.

Be it known that I, RICHARD A. Beans, -a citizen of the United States,residing at San Bernardino, in the county of San Bernardino and State ofCalifornia, have in{ 'vent-ed certain new and useful Improve- Inents inVVave-lilotors; and I do hereby declare the following to be a full.clear, and exact description of the invention. such as 'it appertains tomake and use the same. The primary object of this invention is toprovide an extremely simple and practical invention is to provide in awave motor. an oscillating cylinder. a piston operable with' in: saidcylinder, a piston rod extending outwardly therefrom and having securedto its the' vaves, and novel means 'for supporting the tree end of thepiston rod so that the plate willalways remain substantially at the\Vith these and other objects in view as will hecoine more apparent asthe descr ptain' novel features of construction, coin- "bintiilfill andarrangement of parts as will claimed.- For a complete understanding ofmy invention, reference is tobe had to the following description andaccompanying draw:

Figure 1 is a perspective viewof my improved wave motor parts thereofbeing shown in' section and Fig. 2 isa detail sectional view of one ofthe airtight floats.

Referring in, detail to the drawings by numerals, 5 designates, as"anentirety, :1 cylinde gmounted to oscillate between support ing'legs 6and formed-with an intake port 8 and a discharge port 7, the formerbeing surroundedby a nipple 9 housing a check valve. 10, and the latterbeing provided with acheck valve-l1 opening in a direction op,-

pipe 12 connects the nipple!) with a storage tank '13 which may belocated in any dethe head 17 after it has been forced ii A piston head14' operates withinlthe-cyl indor 5 and has connected to its outer facePatented Maylg, 1914'.

.a piston rod 15 which extends throu h a bearing 16 secured to the head17 of the cylinder. A coil spring 18 surrounds the piston rod 15 andbears at one end against thehead l? and at its other end against-thetransverse pin secured tto the. rod 15. This s 'iringdraws the pistonhead litoward iwardly. by the waves in a manner to be hereinafter-described.

The piston rod extends over a body of water and carries upon its 'freeterminal a plate 20 against which the waves impinge as;the v roll inwardand"as theyrecede. At the ends of the plate 20. inwardly extendingflanges 21 are provided and to the lower edges of these flanges I securefloats 22 which hold the plate normally in-a-substan-" tially horizontalposition,-so as to best receive the action of the waves. To guidethepiston rod 15 and support the lifting meehanism for the plate 20 Iprovide a pair of standards 23 which aredr'iven intothe earth orfjonopposite sides ofthe rod near the outer end thereof. The ,upper ends ofthesestandards' are. extended outwardly in a horizontal" plane in spacedrelation tofo-rm arms 24 between-which a sheave-or roller 25 journaled'on an axle 26-. A flexible connection 27 runsover the sheave orpulley-25 and under a grooved pulley 28 supported under one of the arms24 by an angular bracket 29. The outer end of the flexibleconnection 27is connected by flanges 30 to the end of the plate 20 as clearly shownin the drawings.

A; shaft '31'projects laterally from the upper .end of one of thestandards 23 and supports a pair of pulleys 32 arid33. A lsecond shaft34'is connected to the. IsastL-nintio d'standard 23 directly undertheshaft :31 b low the sur face of thewhter, and has jour naledtheregrqoved rollers or I onza grooved roller or pulley 35 in the samevertical plane as the pulley .33. An end-less cable or other flexiblemember 86m ns around the pulleys 3.3,,and 34 and has fixed to one leaidthereof a float 37. This float isformed with an openint 38 through whichthe other lead ofthe endless ie'able'passes, so that the float when"actuated by the rise 'andftall of the tide, will"move=in a verticalplane and" I beguiddxib'y the cable. A counterbalance weight -39 issecured to the lead40 of thecable- 36, and the inner end of theeonneci vtion after being passed over the pulley 83, is athdi'ed thereto. -Theconnection 27 is of sucli'l ileng'th as to hold the plate 26 in the samehorizontal plane as the float 37, and as this float always remains onthe surface oflthe water, the late will be in proper position to receivet 'e full force of the l operation, waves impinging against t-" -i late20, force the piston head 14 inwar 1y, causing the vvalve to open andthe vdlve 11 to close,whoreby air is forced into the tank orreservoir-13a The spring 18 returns thepiston 14 to its outward positionafter a wave'has passedjby the plate 20, and the next wave again forcesthe piston head inwnrdly,'and thus it will be seen that a continnitusreoiprocatory action of the piston i between 'the plate-and rod.-

I While I "have shown and described the preferred embodiment-of myinvention, it will begunderstood-that 'minor changes in construiwion',combinagion 'and arrangement of parts may be ma, e without departingfrom the spirit aridscope of the invention as claimed. V

Having thus described my invention, I claim a 1. In a wave motor, anoscillating cylin der, a piston arranged within said cylinder, a pistonroddmeans on the end of said piston rod for receiving the impact of thewaves, and means for guiding and supporting the piston rod comprising apair of standards positioned on opposite sides of the piston rod withinthe water, an endless cable supported in a vertical plane by one ofsaidstandards, a float secured to one lead of the cable, apulley-journaled between the, upper ends of said standards, and aflexible con nection secured to the impact receiving means and to theother lead of said cable, the connection passing around the pulley.

2. In a wave motor, the combination of an oscillatin cylinder, a pistonarranged within said cy inder, a piston rod, means secured to the outerend of said piston rod for re ceiving the impact of the waves, and.guide and supporting means comprising a pair of standards arranged inthe water on opposite sides of the piston rod, said standards beingformed with outwardly projecting arms on their upper terminals, a sheavejournaled between said arm, a pair of pulleys secured to one o ftsaidstandards, an endless cable -running around said pulleys, a floatsecured to one lead of the cable, and a flexihle'comiection secured tothe impact receiving means and to the other lead of the cable,saidconnection passing over the sheave.

3. In a wave motor, an oscillating cylinder. a piston arranged witliin=said. cylinder, a piston rod, means on the end of said piston rod toreceive the impact ofthe waves, a pair of standards ah-ranged within theWater on opposite sides of the piston rod and formed on their upperterminals with outwardly extending arms, a sheave journalcd between thefree terminals of said arms, a pair of shafts projecting laterally fromone of said standards, a pair of pulleys secured to the upper of'saidshafts, a third pulle secured to the lower of said shafts, an en lesscable running around said last mentioned pulley and the correspondingpulley on the upper sl'lnft, a float secured to'one lead of said cableand having an opening through which the other lead passes, a

cmintcrbalanee weight secured to the cable on the second mentioned leadand a flexible connection secured to the ill] act receiving means and tosaid weight, t e connection passing over the sheave and one of the pul-'leys on the upper shaft.

In testimony whereof I afiix my signature in presence of two witnesses.
